The next time you are asked how high Triglav, the highest peak in Slovenia, is, the correct answer will no longer be 2864 meters, as we were taught in school, but 2863 m! According to the new official measurements, Triglav is 34 centimeters lower than we thought, which is the height of two steps. The measurement is the result of the transition to a new system of geodetic measurement, which provides the Geodetic Administration with more accurate data on the topology of the surface. The new height system no longer has its starting point in Trieste, and the result is that other peaks will also receive height corrections, albeit small ones. But what is little for Triglav, in the case of floods, 34 centimeters can be a decisive difference.
